Nonanoic acid

Nonanoic acid is a fatty acid which occurs naturally as esters are the oil of pelargonium. Synthetic esters such as methyl nonanoate are used as flavorings. Pelargonic acid is an organic compound composed of a nine-carbon chain terminating in a carboxylic acid. It is an oily liquid with an unpleasant rancid odor. It is nearly insoluble in water but well soluble in chloroform and ether.
